Myriad MCP Orchestration

Overview

Use this skill to run Myriad through MCP clients with predictable tool sequencing and safe write execution behavior.

Server Setup

1. Launch MCP server.

myriad mcp

2. Use STDIO MCP client configuration.

{
  "mcpServers": {
    "myriad": {
      "command": "myriad",
      "args": ["mcp"]
    }
  }
}

3. Confirm tool inventory matches expected names.

• markets_list, markets_show
• users_portfolio, portfolio
• wallet_balances
• swap_stable
• trade_buy, trade_sell
• claim_winnings, claim_voided, claim_all
• ob_markets_list, ob_markets_show, ob_markets_orderbook, ob_markets_trades
• ob_events_list, ob_events_show, ob_events_orderbook, ob_events_actions
• ob_limit_buy, ob_limit_sell, ob_market_buy, ob_market_sell
• ob_orders_list, ob_orders_show, ob_orders_cancel, ob_orders_cancel_all, ob_orders_cancel_batch
• ob_positions_list, ob_positions_split, ob_positions_merge, ob_positions_neg_risk_split, ob_positions_neg_risk_merge, ob_positions_redeem

Safe Tool Orchestration

1. Discover first, write second.

• Call read tools (markets_*, portfolio, wallet_balances) before writes.

2. Use dryRun for all write-capable tools on first attempt.

• swap_stable, trade_buy, trade_sell, claim_winnings, claim_voided, claim_all.

3. Re-run without dryRun only after validating quote/payload assumptions.

4. Keep signer control server scoped.

• Never assume private key override is allowed per tool call.
• Only apiBaseUrl and apiKey are valid per-call API overrides.

Safe Sequences

For AMM workflows:

1. markets_list or markets_show
2. wallet_balances and portfolio
3. trade_buy or trade_sell with dryRun=true
4. Repeat the validated write call with dryRun=false

For order book workflows:

1. ob_events_list/ob_events_show for grouped events, or ob_markets_list/ob_markets_show for binary markets
2. ob_events_orderbook/ob_events_actions for event context, or ob_markets_orderbook/ob_markets_trades for a sibling market
3. wallet_balances and ob_positions_list
4. ob_limit_* or ob_market_* with dryRun=true
5. ob_orders_*, ob_positions_*, and ob_positions_neg_risk_* for post-trade management

API Override Rules

• Allowed per call: apiBaseUrl, apiKey.
• Disallowed per call: signer private key and other undeclared fields.
• If a call returns schema validation error, remove unknown fields and retry.

Failure Handling

• Tool call isError=true: Inspect returned text and structured payload, then retry with corrected arguments.
• Unknown field rejection: Validate against tool input schema and only pass documented keys.
• Server startup issues: Confirm CLI is installed/build is available and command path is correct.

Boundaries

• Do not perform wallet keychain remediation here; hand off to /myriad-wallet-ops.
• For detailed trading policy decisions, hand off to /myriad-trade-execution.
• For order book-specific execution policy, hand off to /myriad-orderbook.
